Answer: 1 = Heat
2=gas
3=it gets hot enough to boil because the metal conducts the heat into the water to heat it up and eventually boil.
Explanation: its common sense
Answer: Systems thinking is a holistic approach to analysis that focuses on the way that a system's constituent parts interrelate and how systems work over time and within the context of larger systems.
Answer:
Speed in kilometer/hour = 6 kilometer / hour
Explanation:
Given;
Time taken to cover distance = 15 minute = 15 /60 = 0.25 hour
Distance of school = 1.5 kilometer
Find:
Speed in kilometer/hour
Computation:
Speed in kilometer/hour = Distance / Time
Speed in kilometer/hour = Distance of school / Time taken to cover distance
Speed in kilometer/hour = 1.5 / 0.25
Speed in kilometer/hour = 6 kilometer / hour
Answer:
D. 30m/s
Explanation:
According to the equation of motion
v=u +at
v = Final velocity
u = initial velocity
a = acceleration
t = time taken
Since we don't know the acceleration of the body, we will find its acceleration using newtons first law of motion F = ma
10000 =2000a
a = 5m/s²
initial velocity = 0m/s since the body starts from rest
v is what we are looking for
t = 6seconds
Substituting this datas in the formula
v = 0+ 5(6)
v = 30m/s (D)
